To all whom it my concernf Be it known that I, MARrr'N C. NEUNER, a

citizen of the United States, residing at Los Angeles, inthe county of Los Angeles and State of California, haveinvented. a new and useful Improvement in Loose-Leaf Binders,

of which the following is a specification.

This invention relates to binders for loose leaf records, and the main objectof the invention is to facilitate the insertion of leavesv in the binder. v

Another object of the invention is to'provide means for permanently locking the binder when it is full or when no more sheets.

1 manner as to cause the rear edges of openings are to be inserted therein.

,, invention:-

Figural is a perspective of the binder in open position.

Fig. "'2, is a similar view showing the binder clamp. in closed position. Fig; 3 is an end elevation of the clamp portion of the binder in open position. Fig. 4 is a similar view "thereof in ciosed position. Fig. 5 is a perspective of the 0 crating and locking means for the clampocking bar. Fig. 6 is a similar view to Fig. 5 showing the operating means removed, leaving the bar in locked condition. Fig. 7 is a fragmentary plan partly in section, of the locking bar case with the bar in position which it occupies when the binder is being used. Fig. S'is a similar view, showing the "position of the barin permanent locked condition.

l'designates the back member of .the binder, the same being formed inround or channel shape, the binder covers 2, 2, being connected by the book-back portion 3 which is secured to said back member 1.

At one side onedge of the back member 1 is pivoted or hinged by pivots 4, a bar 5 carrying studs or pins 6 for engagement with the paper or leaves, thelatter being suitably perforated tofit over said pins the pivots 4 extending parallel to the back member to enable the bar 5 to swing transversely to the back and cover members. At the other side or edge ofthe back member 1 is pivoted orhinged at 7, a member 7 formed as a case or -carrier for the locking bar 8 which slides The accompanying drawings illustrate the tion 14, see Fig. 5, which engages in a seat 15 in the locking bar to cause the locking; bar to traverse longitudinally in the case 7 when the-lever 'l2 is raised. or lowered. -When. the lever is raised the locking bar is pulled back, leaving the perforations therein 1n register with the perforations 1 Lin the case 7, permitting free entry or withdrawal of the pins fi. When the lever 12 is depressed it slides the locking bar along the slot in such 9-to engage the notches 10 in the pins 6 and prevent withdrawal of said pins.

A retaining bar 16 may be provided, the same having L-shaped slots or notches 16 whereby the bar may he slipped over the ins i 6, and iclamp members 17 ingjpivote to the saidbar 16, andhaving cam lugs 18 which maybe swun be slipped up and down on the pins-to clamp the paper tightly, or it may be brought into engagement with the pins, as shown in Fig. 2, to clamp said retaining bai' tightly in place. In inserting leaves into the binder the hinged bar'5 may be turned back against the cover so that the pins '6 project in position to facilitate placing the leaves thereon.

a To THE NEUNER SPEOiAL'lY' is pivoted to the case 7, and has a cam por- L clear of the pin, as shown-in Fig. 1 to ena lo the retaining bar to Thence the bar maybe turned to cause the pins to cross or bridge the back member, the locking bar being first'turned away to enable this movement and being then turned toward the pins toengage the same.

It is desirable msome cases to provide for permanently locking theleaves in place after the binder has been filled or therecord is completed; For this purpose I havemade the pivot 13 of the lever 12 removable; the

same consisting, for example, of a screw. A permanent lock for the bar 8 is provided, consisting of adug or projection 19 extending inwardly from one Wall of the case 7. In normal operation of the o crating lever 12, the

end of the locking bar oe's not pass thisprojection and the latter is without effect, but onremoving the screw 13 the lever 12may be removed and the bar may then be pushed to bring its end beyond the projection 19. This is accomplished by the use of any suitable instrument by the operator. In'the normal or usual operation of the parts the inward projection 19, see Fig. 7, rides on the bar 8, the wall of the case yielding by its elast'ihity sufliciently to" permit this movement, but when the bar 8, is pushed all the way in, as shown in Fig. 8, the wall of the case will resume its natural position bringing the lug 19 in the rear of the bar 8, as shown in Fig. 8, and preventing, outward movement of the bar. It will be understood that at this time the binder" will be full of aper which will press the locking bar in sue a manner as to old itagainst the side of the case carrying the projection 19', and this, together with the friction of the parts, will aid in preventing the withdrawal of the bar when it has once assumed this position.

In loose leaf binders,.neatness of the completed book is very desirable as ;-well as strength and compactness. By utilizing a round or channel shaped metal back member 1 and hinging the stud or pin bar 5 to the edge of this plate and inde endently of the 1 am enabled to binder covers 2, 2, and boo r-back portion 3,

rovide a much neater binding as well as a binding of great strength and com actness. Another advantage secured byt is construction is avoiding the necessity of the studs or ins 6 projecting through the covers 2, 2. l urthermore with such construction it is possible to construct account books having the same general shapes and styles of the standard bound books which have no shar edges or corners to scratch or mark the surtaces u on which they are used. The use of the roun or channel shaped metal back memberl also enables the use of a number of small metal hinge connections between the edge of the member 1 and the platelor bar 5, thus securing great strength,,whic hcould not be secured'lf the bar o'r plate 5 were'eo'nnected to a flexible portion of the cover so as 1 to form a flexible hm e, andalso rovides a stiff back for the boo relieving-t e "greater portion of the strain, where the book no en and in use, from the pins or studs 6Q y thus hinging the in bar 5 to the back member 1, it is possib e. to swin all the leaves on the pins over so they rest at'and admit the ready addition of further leaves without any chance of any leaf slipping oil any of the studs or pins 6, such leaves being most read-,

ily slipped u on the studs or pins when the latter Lexten up vertically. Furthermore,

the'hinging or pivoting of the pin bar 5 obviates any necessity of using open topped slots in the locking-bar case 7. The use of an inclosed case permits of the use of a sliding locking-bar 8 without the necessity of providing a mounting for the latter upon the hinged plate, as by studs and elongated slots. The use of theinclosing case 7 also renders ossible the use of concealed means for lockmg the bar 8v to prevent return movement.

What I claim is:- 1. A loose-leaf binder comprising a leafengaging member, a movable locking member therefor, an operating nieans for the lockingmember having a limited movement, said operating member bein removable to allow further movement of tie locking member, and means engaging the locking member to lock the same on such further movement.

2. A loose-leaf binder-comprising a-leaf:

engaging member, a locking member there? for, a case wherein the locking member 1s slidably mounted, a lever detaclrably pivoted on the case and engaging the locking member to move the same longitudinally a limiteddistance, the lockin .member being movable a further distancew en the lever is removed,

and a projectionfinthe case engaging the 'lOQklI'lg member on such further movement,

to" revent back movement thereofl Y n testimony whereof, I have hereunto set my hand at Los Angelcs, Californiathis 15th day of May 19.05.
